Product Overview

Figure 1 - WEL-200T (transmitter)

Figure 2 - WEL-200R (receiver)

The EMX WEL-200 system provides a complete wireless solution for interfacing sensing

edges with gate and door operators, while ensuring compliance with 2016 UL325

monitoring standards. Each transmitter can run for up to two years on two AA lithium

batteries. The receiver connects with up to four transmitters, with separate relay and

pulse outputs for open and close edge functionality.

With enhanced diagnostic features, the WEL-200R will make installation and

maintenance easy and reliable. Feedback is provided for all fault modes, including

edge open and short conditions, low battery, and failed transmitters.

Operation

1. Receiver Installation

The receiver enclosure can be mounted to the exterior of an operator using four (4) #8 machine

screws, washers, lock washers, and nuts. Ideally, it should be placed in direct line-of-sight with the

transmitters, with no obstructions between the WEL-200R and the WEL-200T.

1. Mount the receiver.

2. Determine the monitoring method required by the operator.

3. Remove the cover. If the monitoring method is using relay contacts, then set the internal DIP

switch settings for each channel to either OPEN or CLOSE direction relay function depending on

the location of each edge.

4. For 10K resistive monitoring, place the jumper in the 10K position for both OPEN and CLOSE

direction relays.

5. Pulse outputs are available for open collector pulse type monitoring.

6. Wire the appropriate output to the operator.

7. Connect the power to power terminals.

2. Connecting

Connecting is a two step process. First, on the receiver, press and hold the channel assignment

switch until the green status LED begins rapidly flashing, then release; this will clear any existing

assignment for that particular channel. Hold down the connection switch on the transmitter. If it

is not currently connected to a receiver, it will begin flashing rapidly until successfully connecting.

Detailed instructions are given below.

2.1. Apply 12-24 VDC/VAC to the WEL-200R (receiver), wait for initialization to complete1

2.1.1. If there are no existing connections, the receiver’s status LED will blink rapidly while it is finding a clean operating frequency (this can last a few seconds)

2.1.2. After initialization, the system status LED will flash on/off once every 2 seconds

2.2. Set channel to the desired OPEN/CLOSE direction function using the MODE dip switch

2.3. Install 2 AA Lithium batteries in the WEL-200T (transmitter)

2.3.1. The green LED on the transmitter will quickly flash 2x every two seconds


2.4. Install a properly terminated edge to the transmitter (8.2k or 10k termination)

2.5. On the receiver, hold down the desired channel assignment switch until all four channel LED’s activate and the system status LED begins flashing rapidly, then release the switch.2

2.6. On the transmitter, hold down the connection switch (next to the terminal block)3

2.6.1. The LED on the transmitter will begin flashing rapidly after ~4 seconds

2.6.2. Upon successful connection, the LED will flash once every two seconds

2.6.3. If the transmitter fails to connect, it will return to its initial state, with the LED

flashing twice every two seconds. If this occurs, repeat step 2.6. If the transmitter will not connect, proceed to the troubleshooting section.

2.7. Testing

2.7.1. Without activating the edge, observe the channel status LED, it should be OFF.

2.7.2. When the edge is activated, the receiver channel status LED will turn on and

the corresponding OPEN/CLOSE direction output will activate. The transmitter

status LED will blink once every second when the edge is activated.

2.7.3. If the channel does not exhibit this behavior, double check the edge

wiring/termination and transmitter batteries.

Notes

1. If channel 1 and 4 switches are pressed simultaneously during power up, the receiver will

perform a factory reset and clear all programmed channels.

2. Channel assignment mode will exit under the following conditions:

a. Successful connection to a transmitter

b. 60 second timeout

c. User selected exit

i. Pressing channel 1 and 4 switches simultaneously for more than 2 seconds


3. To remove a connection from the transmitter, hold down the connection button. The

LED will turn on solid for several seconds, and then blink twice every 2 seconds when

disconnected.

Troubleshooting

Under normal operation, the WEL-200R STATUS indicator LED will flash once every two seconds.

This is referred to as a cycle (one second on/one second off). Any fault that occurs will cause the

associated open/close output to change state. Output state refers to the output assigned to the

channel via the OPEN/CLOSE switch on the receiver. The main faults indicated by each channel

LED are as follows:

The system status LED (next to the power LED) can be used to compare the flashes. The LED for an

unassigned channel will flash at the same rate as the status LED.

When channel assignment mode is entered, the active channel’s LED will turn on for 0.25

seconds, once per cycle.

If the edge resistance is above normal, due to lack of/improper termination or cable

damage, the offending channel’s LED will turn on for 0.25 seconds, 2x per cycle.
